What should your oxygen saturation be? What are normal and safe oxygen levels? How does a finger pulse oximeter work? Learn about blood oxygen levels, symptoms of low oxygen (hypoxemia), and ways to keep your blood oxygen levels in the normal range, with charts.
A normal reading typically ranges from 95% to 100%. Levels below 92% are considered low and could indicate a more serious issue, so contact a healthcare provider. Seek immediate medical attention for a reading of 88% or lower.
A normal range for your blood oxygen level is between 92% and 100%. SpO2 readings can fluctuate based on activity, overall health, and other factors. Your body relies on a coordinated effort between your heart, lungs, and circulatory system to maintain a healthy blood oxygen level.
Oxygen saturation levels (SpO2) between 95 to 100 percent are considered normal for both adults and children (below 95% is considered abnormal). People over 70 years of age may have oxygen levels closer to 95%.

A healthy blood oxygen level is 75–100 mm Hg, or 95–100%. Low blood oxygen levels, known as hypoxemia, may be a cause for concern. Your blood oxygen level is a measure of how much...
For most people, a normal pulse oximeter reading for your oxygen saturation level is between 95% and 100%. If you have a lung disease such as COPD or pneumonia, your normal oxygen saturation level may be lower. Your healthcare provider will let you know what levels are acceptable.
Pulse Oximeter Readings. Oxygen levels are measured in relation to the percentage of oxygen saturated in your blood. In medical terms, this is your SpO2 level. Normal Blood Oxygen Levels. The normal blood oxygen saturation rate is between 95% and 100%. ‘Concerning’ Blood Oxygen Levels

Summary. Your oxygen levels indicate how well your heart and lungs are delivering oxygen to support your body’s essential functions.
Normal oxygen saturation levels as measured by pulse oximetry are 95 to 100% for adults. If your oxygen saturation drops below 90%, you may need medical treatment and supplemental oxygen. Why is pulse oximetry performed? Pulse oximetry can quickly, easily and painlessly measure blood oxygen levels.
